How much do you know about the inverter wiring specifications? The signal line and the power line must be routed separately: when using analog signals to control the inverter remotely, in order to reduce the interference of the analog quantity from the inverter and other equipment, please control the signal line and the strong circuit (main circuit) of the inverter And sequence control circuit) separately. Inverter wiring specifications, the distance should be above 30cm. Even in the control cabinet, such wiring specifications should be maintained. The maximum length of the control loop line between this signal and the inverter shall not exceed 50m.

The signal line and the power line must be placed in different metal pipes or metal hoses: if the signal line connecting the PLC and the inverter is not placed in the metal pipe, it is extremely susceptible to interference from the inverter and external equipment; There is no built-in reactor, so the input and output power lines of the inverter will have a strong interference to the outside, so the metal tube or metal hose where the signal line is placed must be extended to the control terminal of the inverter to ensure the signal line Completely separated from the power line.

Inverter wiring specification one, the analog control signal wire should use double stranded shielded wire, and the wire specification is 0.75mm2. When wiring, please pay attention that the cable stripping should be as short as possible (about 5-7mm), and the shielding layer after stripping should be wrapped with insulating tape to prevent interference between the shielding wire and other equipment.

Inverter wiring specification two, in order to improve the simplicity and reliability of wiring, it is recommended to use a crimp terminal on the signal line.
